A 16 GB DDR4 ECC UDIMM kit with two 8 GB modules at 2400 MHz CL17 for servers and workstations

  • CAS latencyCL17
  • Memory rank1Rx8
  • 16 GB dual-channel kit doubles throughput
  • ECC UDIMM detects and corrects single-bit errors
  • Single-rank 1Rx8 layout improves memory-controller efficiency

  • Standard 1.2 V DDR4 voltage reduces power draw

16 GB DDR4 ECC UDIMM kit

This 16 GB kit contains two 8 GB DDR4 ECC unbuffered DIMMs built for servers and workstations that require error-correcting memory. Each module runs at 2400 MHz with a CAS latency of CL17 and operates at the standard 1.2 V. The single-rank 1Rx8 organisation helps keep signal loading low on supported platforms.

Straightforward DIMM installation

The 288-pin modules seat in standard DDR4 DIMM slots exactly like non-ECC UDIMMs, so no special tools or cables are required. The most common issue is attempting to use these modules in a desktop or laptop that does not support ECC unbuffered memory, which will prevent the system from posting. Follow the motherboard manual for correct slot population and channel guidelines.

Verify ECC UDIMM support first

Before ordering, confirm that your server or workstation explicitly lists DDR4 ECC unbuffered UDIMMs in its qualified vendor list or hardware manual. Systems that only accept registered DIMMs, non-ECC memory, or a different voltage will not work with this kit. Check the maximum supported speed and total capacity per channel to match the 2400 MHz rating and 16 GB total.

Questions about this item

How do I confirm the kit is running at 2400 MHz with CL17 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report DDR4 2400 MHz and CAS latency 17 for each 8 GB module.

What comes in the box and do I need any extra parts?

The package contains two 8 GB DDR4 ECC UDIMM modules; no additional components are required if your server or workstation has free 288-pin DIMM slots.

Should I choose the PC4-19200 or PC4-2400T-E labelled version?

Both labels describe the same 2400 MHz DDR4 specification; select whichever matches your system's qualified vendor list.
